BACKGROUND

1. Technical Field

This disclosure relates to dietary compositions that can aid in weightloss efforts. In particular, this disclosure provides dietarycompositions containing a natural protein extract derived from potatoes,a beta glucan source, a dairy protein source, and optionally inulin.

2. The Relevant Technology

The population of people considered “overweight” has reached epidemiclevels, which not only increases the risk of disease in thoseindividuals, but also puts a strain on the healthcare industry as awhole. In fact, obesity is considered by some health authorities to be aleading cause of disease throughout the world, and particularly theUnited States. One approach to combating obesity is through theadministration of healthy dietary compositions. Dietary compositions forcombating weight gain and obesity can include foods, medicinalingredients, extracts, herbs, and other forms of matter that can beingested or otherwise absorbed by some part of the human body.

BRIEF SUMMARY

This disclosure provides dietary compositions configured to enhanceweight loss efforts and increase health by increasing satiety in a userconsuming the dietary composition. The disclosed dietary compositionsincrease satiety by both increasing the physical feeling of fullness inthe stomach (over and above that caused by the volume of food consumed)and simultaneously promoting the release of cholecystokinin (CCK), ahormone that reduces hunger in the consumer. A user consuming theprovided dietary composition in conjunction with a carrier food source(e.g. a shake, bar, or soup), or an additional food, will perceivefeelings of satiety above that which would be perceived in the absenceof the herein provided dietary compositions.

In certain embodiments, the dietary compositions contain a naturalprotein extract derived from potatoes, beta glucan, a dairy proteinsource such as whey protein, and optionally inulin. In some cases, adietary composition provided herein can include SLENDESTA™ brand proteinextract, oat beta glucan, barley beta glucan, inulin, and whey proteinisolate.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

In general, this disclosure provides dietary compositions configured toenhance weight loss efforts by increasing satiety in a user consumingthe dietary composition. The disclosed dietary compositions increasesatiety by increasing the physical feeling of fullness in the stomach(over and above that normally caused by the volume of food consumed) andsimultaneously directly providing peptides and promoting the release ofpeptides that reduce hunger in the consumer and otherwise stimulatefeelings of fullness. For example, this disclosure provides dietarycompositions containing a natural protein extract derived from potatoes,beta glucan, a dairy protein source such as whey protein, and optionallyinulin.

With reference to the specific ingredients for use in the discloseddietary compositions, any form of a natural protein extract derived frompotatoes can be included. The potato protein extract preferably includesas its active component Proteinase Inhibitor II (PI2). Although thepresent invention is not limited by any particular theory, PI2 isbelieved to promote the release of CCK, a natural signaling peptidewithin a human body. Once released, CCK can travel through the bloodtargeting various organs, where it induces feelings of fullness andsatisfaction, i.e., satiety. One non-limiting source of the naturalprotein extract is SLENDESTA™, a natural satiety ingredient for weightloss that is derived from white potatoes and sold by Kemin Industries,Inc. under the trademark SLENDESTA™. SLENDESTA™ is potato proteinextract can be standardized to its active component Proteinase InhibitorII (PI2). Further details regarding SLENDESTA™ can be found in U.S. Pat.Nos. 6,872,544, 6,767,566, and 6,686,456, each of which is incorporatedherein by reference.

A dietary composition provided herein can contain any amount of thenatural protein extract derived from potatoes. For example, a dietarycomposition can contain from about 0.01 μg to about 0.06 g (e.g., fromabout 0.01 μg to about 50 mg; from about 0.01 μg to about 10 mg; fromabout 0.01 μg to about 1 mg; from about 0.01 μg to about 750 μg; fromabout 0.01 μg to about 500 μg; from about 0.1 μg to about 60 mg; fromabout 1 μg to about 60 mg; from about 100 μg to about 60 mg; from about500 μg to about 60 mg; or from about 1 mg to about 50 mg) of SLENDESTA™or other natural protein extract derived from potatoes.

In some cases, a dietary composition can contain about 0.1,0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 30, 35, 40,45, 50 percent or more of a natural protein extract derived frompotatoes, about any percentage of a natural protein extract derived frompotatoes between these enumerated percentages, or any range ofpercentages of a natural protein extract derived from potatoesencompassing one or more of these enumerated percentages (e.g., fromabout one of the enumerated percentages of natural protein extractderived from potatoes to about another of the enumerated percentages ofnatural protein extract derived from potatoes).

In certain embodiments, dietary compositions provided herein alsoinclude beta glucan. Beta-glucan is a natural polysaccharide made ofglucose. For example, a dietary composition can include oat beta glucan.Oat beta glucan can increase the viscosity of stomach contents, whichcan slow stomach emptying, prolong the absorption of energy from a meal,and decrease the absorption of fat. These effects can exert strongcontrol over insulin release in the body, which can reduce cholesterolproduction, extend satiety, and benefit heart and glycemic health. Anytype of beta glucan can be included in a dietary composition providedherein. Examples of beta glucan include, without limitation, oat,barley, wheat, and other beta glucans. Beta glucan can be in any form,for example, a solution, a powder, or a soluble powder.

A dietary composition provided herein can contain any number ofdifferent beta glucans. For example, a dietary composition can containone, two, three, four, five, six, seven, eight, nine, ten, or moredifferent beta glucans. Any appropriate method can be used to obtainbeta glucans. For example, water can be used to obtain a preparation ofbeta glucan. In some cases, beta glucan can be extracted fromnaturally-occurring sources. A dietary composition provided herein cancontain any amount of a beta glucan. For example, a dietary compositioncan contain from about 0.01 μg to about 5 g (e.g., from about 0.01 μg toabout 5 g; from about 0.01 μg to about 2.5 g; from about 0.01 μg toabout 1 g; from about 0.01 μg to about 750 mg; from about 0.01 μg toabout 500 mg; from about 0.1 μg to about 1 g; or from about 1 μg toabout 500 mg) of beta glucan. In some cases, a dietary composition cancontain about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,18, 19, 20, 21, 22, 23, 24, 25, 30, 40, 50, 60, 70, 80, 90, 100, 200,300, 400, 500, 600, 700, 800, 900, 1000, 1500, 2000, 2500 mg or more ofbeta glucan, about any amount of beta glucan between these enumeratedamounts, or any range of beta glucan amounts encompassing one or more ofthese enumerated amounts (e.g., from about one of the enumerated amountsof beta glucan to about another of the enumerated amounts of betaglucan).

Aqueous carriers include, withoutlimitation, water, alcohol, saline, and buffered solutions. Acceptablecarriers also can include physiologically acceptable aqueous vehicles(e.g., physiological saline) or other known carriers appropriate tospecific routes of administration.

In some cases, the dietary composition can be included as a supplementin a carrier food form, for example in the form of a shake, bar, orsoup. For example, a blend of ingredients provided herein can beincorporated into a base of soy crisps, syrups, sweeteners, and fibersources to produce an extruded protein bar. In some cases, the productcan be in the form of a chocolate bar (e.g., a chocolate protein bar) ofsubstantially uniform consistency. The chocolate bar can be darkchocolate, light chocolate, white chocolate, any other type ofchocolate, or a mixture thereof. For example, a dietary composition canbe in the form of a dark chocolate bar. Dark chocolate is known tocontain cacao, a substance known to contain over 300 identifiablecompounds including protein, fiber, iron, zinc, copper, calcium,magnesium, and high levels of potent antioxidants. Optionally, caramel,peanut butter, or any of a variety of other flavorings or food productscan be added to the bar. A bar can be, for example, about 50 grams inweight, and can provide one serving of pre-blend. A bar can be ofgreater or lesser weight (e.g., 25 or 100 grams), and can provide moreor less and one serving of pre-blend (e.g. half a serving or twoservings). The product can be coated or partially coated in chocolate(or other flavor), and each bar can be individually packaged. Theproduct can be coated or partially coated in dark chocolate, lightchocolate, any other type of chocolate, or a mixture thereof. The finalproduct can be consumed as one serving as either a meal replacement orsnack item.

In another example, a blend of ingredients provided herein can be addedto a meal replacement shake base. The configuration of a suitable shakebase is known in the art and will be apparent to one skilled in the artin view of the disclosure herein. The final shake can be any flavor(e.g., chocolate, vanilla, or strawberry). Final serving size can be,for example, 30 g to be dispersed into 8 ounces of milk or water (orother suitable liquid) to form one complete serving. Final serving sizecan be greater or lesser than 30 grams (e.g., 15 or 60 grams) and canprovide more or less than one complete serving (e.g., half a serving ortwo servings).

In some cases, dietary compositions provided herein can be provided to asubject for ingestion as stand alone supplement forms, such as tabletsor capsules, in addition to being provided as shakes or bars, toincrease the amount of oat beta glucan, barley beta glucan, inulin, wheyprotein, natural protein extract derived from potatoes, or any otheringredients in the dietary composition consumed by the subject.

As described herein, a dietary composition can be used to aid in weightloss in a mammal. Weight loss can be examined using any appropriatemethod. For example, by using a weight scale. A human's weight can becontinually or intermittently monitored over a period of time, e.g.,once a day, once a week, once a month. A weight trend may indicate theeffectiveness of a dietary composition in lowering a human's weight ormaintaining a healthy weight.
